SPECIFICATION forming part of Letters Patent No. 664,911, dated January 1, 1901.

Application filed September 17, 1900. Serial No. 30,304. (No motlel To @ZZ whom, it may concern:

Beit known that I, WILLIAM H. Voss, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have inventedcertain new and useful Improvements in Mechanical Movements, of which the following is a full, clear, and exact specification.

The object of my invention is to provide a mechanical movement for windmills, churns, washing-machines, ttc., which converts the motion of a continuous-revolving shaft to a shaft arranged substantially at right angles thereto in such manner as to impart to the same a rotary reciprocal movement with a minimum amount of effort and without creating excessive friction. This I accomplish by the means hereinafter fully described and as particularly pointed out in the claims.

In the drawings, Figure l is a side elevation of my invention. Fig. 2 is a plan View of the same. Fig. 3 is a detail view showing the one position of the pinion in connection with a broken-away port-ion of the continuouslywrevolving shaft and the tilting annulus and rack. Fig. 4 is a similar View showing said pinion in another position with relation to said annulus and rack, and Fig. 5 is a vertical longitudinal central section through the rotary reciprocal shaft and mechanism car ried by the same separated from the rest of the machine.

In the drawings, A represents a suitable frame having a base-plate or its equivalent, which is screwed or otherwise secured to its support and is provided with arms in which the continuously-revolving shaft Bis journaled. One of these arms ct is extended beyond the bearing of shaft B to form a gooseneck, the end of which is provided with a bearing for the contiguous end of the rotary reciprocal shaft C. Shaft C extends in a plane substantially at right angles to shaft B, although, as will hereinafter more fully appear, it can, to a limited extent, be set oblique thereto. The opposite end of shaft C preferably extends through its bearings and has attached thereto or connected therewith such mechanism as may be desired to utilize the rotary reciprocal motion of said shaft.

At a lpoint on shaft C in alinement with shaft B it has a spheroidal boss c keyed thereto, the top and bottom poles of which are preferably attened. Surrounding shaft C on both sides of boss c are stationary sleeves d and e, the ends of which next said boss are provided with corresponding convexe-concave bearing-cups d and e', whose edges a; are so inclined that they approach nearest to each other at diametrically-opposite points intersected by a vertical plane striking through the center-of shaft C at right angles to shaft B. From apices thus formed these edges incline in opposite directions at corresponding angles. Surrounding this boss between the bearing-cups d and e is an annulus D, which has a central opening slightly greater in diameter than that of said boss, so as to permit it to move freely upon the same, except as it may be limited by the bearingcups CZ and e' and by the lugs f, projecting radially inward from its central opening into the longitudinal groove g, encircling said boss, which latter permits the annulus to have a stight independent vertical tilting movement, but causes it to revolve therewith.

The annulus D has the greater portion of its perimeter provided with a segmental rack E, which is constructed of a series of equidist-ant corresponding radiating bars h, projecting from said perimeter, that have their outer ends connected by a surrounding corresponding segmental rim m. The perimeter of the annulus from which the bars h project is of a width about three times as great as that of the rim m, and its ends are rounded in a circular plane struck from the center of the end bars of said rack. Between these rounded ends a guide-block G is placed,which,as shown in the drawings, is constructed as though two crescents were placed back to back, with the concaved edges thereof opposite the round endsof the perimeter and concentric therewith.

The end of shaft B extends through the bearing in the arm a of frame A and near its' extremityis provided with a suitable beveled gear or pinion I, the teeth of which engage the segmental rack substantially as shown. The shaft extends slightly beyond the pinion I toward the shaft C, and the relative width of the perimeter of lehe annulus and the diameter of the pinion I are such that this extended end o of shaft B bears upon the edge IOO traveling in the opposite direction.

of said perimeter. As pinion I revolves and the annulus is rotated-say from left to rightthe end o of shaft vB when the end of the perimeter approaches the Vsame enters between the projecting horn of the guide-block G and the round end of the perimeter, whereupon the engagement of the teeth of said pinion with the end har of the rack tilts the contiguous side of said rack, so as to move the same above the pinion and at the same time effects a reversal of the movement of both said rack and annulus and shaft C, by which the same is carried. When the segmental rack and annulus have been moved so that the opposite end of the perimeter thereof approaches the pinion I, the extended end 0 of the shaft B enters the runway between the projecting horn of the guide-block and the curved end of the perimeter and tilts the contiguous side of said rack downward Vand reverses the movement of the same and said an n ulus again.

It is apparent that instead of the segmental rack a double row of teeth extending but partially around the perimeter of the annulus might be used. This is an obvious change, and while not illustrating the same I desire to consider as contemplating it within the scope of my invention.

From the foregoing explanation of the operation of myinvention it is obvious that the segmental rack and annulus are tilted up and down, so as to utilize first the movement of the upper segment of the pinion I traveling in one direction and then the movement of the undermost segment of said pinion while The inclining of the edges of the bearing-cups d' and e' serve to limit the extent of the tilting movement of the segmental rack and annulus; but it is obvious that this feature may be dispensed with and the tilting of the segmental rack and annulus be accomplished in an equally effective manner without the assistance of the same.
